YARN AND THREAD CLEANER FOB "WINDII TG MACHINES.

- Application filed August 16, 1921. Serial No. 482,833.

To all whom it may concern:

*Be it known that I, JAMES D. Joron, citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Yarn and Thread Cleaners for lVinding Machines, of which the following is a specification.

My invention relates to yarn or thread cleaners for winding machines.

The object of my invention is to produce a device for cleaning yarn or thread of knots and slubs before being wound upon bobbins. A further object thereof is to produce a device of the character described adapted to be regulated for use with different thicknesses and grades of yarn or thread and to be attached adjacent to the bobbins of a winding machine on the builder or building post of the winder. Another object of my invention is to provide a yarn and thread cleaner in which the parts may be readily adjusted to compensate for wear and conveniently removed and replaced when desired, and a still further object thereof is to produce a more simple, cheap and efficient device of said character than has heretofore been attained.

To these ends, my invention includes the combination and arrangement of component parts to be hereinafter described and more particularly pointed out in the claims.

In the accompanying drawings, in which like reference characters indicate similar parts, t

Figure 1 is a perspective view of the preferred form of my invention;

Figure 2 is a similar view of a modified form thereof;

Figure 3 is another modified form, and

Figure 4 is a detail perspective view of Fig. 1.

Referring now to Figures 1 and 4a of the drawings, 1 indicates a bracket comprising an arm 2, a flange 3 provided with a screw hole a for attaching same in operating position, a head 5 at the outerend of the arm, and a lateral lug 6 intermediate of its ends.

The head 5 is provided with two transverse sockets a and b in close proximity to each other to removably and adjustably hold the stems of the bar 7 and the blade 8 which project laterally from the bracket.

As shown in the drawings, the bar 7 .is channelled or grooved longitudinally throughout its exposed length to form a seat for the cylindrical glass stem 9, the face of which is exposed below the edge of the channelled bar and is held in close proximity to the cutter or blade 8.

The blade 8, before mentioned, is preferably rectangular in cross section, by which construction four cutting edges are provided which may be alternately adjusted into proximity to the face of the glass stem 9 as they become dulled in use, and it will be apparent that the distance between the glass stem and edge of the blade may be adjusted by turning the blade in its socket and held in position by the set-screw 10 while the bar 7 may be likewise adjusted in its socket and held by the set screw 11 to obtain the preferred relation between said parts, the glass stem 9 being carried slightly off center.

Aguiding finger 12 preferably of porcelain is carried on the lateral arm 13 removably and adjustably secured on the lug 6, as shown.

The yarn or thread to be wound upon a bobbin, passes over the face of the glass stem 9 and is held thereon by the guiding finger 12. The space between the stern and stripper may be regulated by adjusting the turn of either or both in their socket-s to perniit yarn or thread of different grades to freely pass, but sufficiently close to each other that the sharp edge of the stripper will arrest a knot or slub in the yarn and cut the strand. The yarn may then be properly spliced with a weavers knot and the winding continued.

In the modified forms of my invention shown in Figures 2 and 8, the arrangement of the parts are altered from the showing made in Figures 1 and 4 to permit the device to be attached to different structures of winding machines.

In Figure 2, the bracket 1 carries the head 5 in which are three sockets adapted to receive the stems of the bar 7 and stripper 8 and hold them in parallel arrangement and also the arm 13 which, as shown, is curved, and upon the outer end of which is secured the guide 12.

The bracket 1 may be secured in operat ing position by the lateral arm 14. As shown in Figure 3, the plate 1" carries the head 5 from which the bar 7 and stripper 8 project in the opposite direction while 110 the guide 12 is carried upon an arm 6 at a different angle than either shown in Fi ures 1 and 2.

aving thus described my invention, What I claim as new and desire to be secured by Letters Patent, is:

1. In a yarn or thread stripper for winding machines, the combination with a bracket of a laterally extending filament supporting arm having a smooth surface, an arm angu lar in cross section having a plurality of cutting edges adjustably carried parallel to the supporting arm forming an open space between same and the supporting arm the Width of which space may be varied by the adjustment of the cutting arm to permit filaments of different thickness to pass and to be arrested when a knot or slub occurs.

2. In a yarn or thread stripper, the combination with a bracket, of a laterally extending filament-supporting arm. having a smooth surface, an arm rectangular in cross section having a plurality of cuttingedges mounted parallel to the supporting arm forming an open space between same and the supporting arm, and means for adjusting the cutting arm with relation tothe supporting arm whereby the space between same may be changed and the several cutting edges brought into alternate operative relation to the supporting arm, as and for the purposes described.

In testimony whereof I have afiixed my signature.

JAMES DANIEL JOYCE.
